REST API design is one of the most critical and challenging aspects of building a modern platform. It often considers (and leads) the creation of other parts of the system, such as authentication, authorization, and authorization (and much more).
Regarding API design, there are always best practices to follow. There is no one right way of doing things. But following the best practices can help you keep your API running smoothly by minimizing downtime and ensuring that your API remains secure and resilient in the face of attacks from malicious users or outside forces such as DDoS attacks, DDOS, or other types of denial-of-service attacks.
What is a REST API?
REST stands for Representational State Transfer. It represents the interface between a client and server in a distributed system. The purpose of using an API is to make it easier for developers to integrate their applications with external web services.
An API is an application programming interface (API) that provides access to systems, data, and software components over the Internet. An API can be thought of as a set of software functions that a software system exposes to enable users to interact with the system.
There are various kinds of RESTful APIs:
Functional APIs: These APIs provide only read operations. They allow you to use the server to retrieve data or perform actions like creating a new record or updating an existing one.
Content-based APIs: This type of API is based on the concept of converting a resource into an elaborate representation format (JSON, XML). In this model, the client sends a request which contains data in its design along with information about how it should be converted into JSON/XML format by the server before returning it to the client.
Resource-oriented APIs: This type of API uses resources such as files, images, and documents instead of URLs for representing data about them.
REST API Design Best Practices
The REST API Design Best Practices are a set of guidelines that can help you to design and implement your APIs in the best possible way.
They are based on the principles of good web design and will help you to:
● Understand what REST is and why it matters.
● Create APIs that are easy to use, well documented, and don't break when the underlying technology changes.
● Make your API accessible via any programming language or framework.
● Allow for changes in features or functionality without breaking backward compatibility.
Organize the API design around resources
The API design should be organized around resources, not actions.
Actions should be minor units of work that an application can request. They are usually composed of multiple individual requests. The smallest unit of work is a single HTTP request.
Resources, on the other hand, represent a concept in your application that may be related to several actions. For example, if you have a customer account, it may have multiple orders associated with it. An order can be deleted or modified as one action. Still, it has many attributes and may have been created from other data sources and materialized from reports, systems, or applications.
Use Nouns Instead of Verbs in Endpoints
Nouns are usually better than verbs when it comes to REST API design. Verbs are more specific than nouns, but nouns are easier to understand and read. When you have a verb in your endpoint, it can be difficult for the user to understand what exactly you want them to do. In contrast, if you use a noun in your endpoint, people will know what action they should take without reading any additional information about it.
For example, if you were building an endpoint that allowed users to create new posts on your website, using "create" as a verb would be difficult for users to understand because they might think it meant "create something." However, using "add" as a verb would make their lives easier because they know exactly what action they should take.
